Request Info

BLINK High Speed is the latest LaserPoint’s achievement specifically developed to measure ultrafast lasers with pulse duration down to femtoseconds. It is the ultimate solution for whatever application requiring: accurate energy measurements for ultrafast pulsed lasers, monitoring of fast manufacturing processes in production lines, and detection of fast instabilities in ultrafast lasers. BLINK HS patent pending technology, based on thermopile design, makes this product the fastest laser power and energy thermal sensor currently available in the market.

This technology allows combining the high response speed of a photodiode with the broadband and high power operation of a thermopile. Laser applications requiring high speed measurements can take advantage of the sub-microsecond response time; this BLINK HS feature allows measuring the energy of each pulse emitted by laser sources with repetition rates up to 1 MHz, pulse durations down to fs and average power up to 20 W, specifications that cannot be present all together in pyroelectric or photodiode sensors. Moreover, its high-damage threshold allows withstanding energies up to 10 mJ.

BLINK HS can be deployed by laser manufacturers to detect fast instabilities in laser sources as well as by system integrators to monitor fast processes in production lines. Combining all advantages present in photodiodes, pyroelectric, and thermal detectors, BLINK HS is a very versatile product, suited to measure most of the laser sources commercially available, whatever the emitting wavelength (UV-VIS-IR).

High speed electronics is also available with a sampling rate up to 500 Msample/s to provide a precise energy measurement of each single ultrashort pulse. The High Speed Meter HSM-1000 allows to interface BLINK HS sensor to a standard PC via Ethernet using GIOTTO Software for data visualization and statistical analysis
